Has anyone designed FAA & Department of Transportation certified computer programming etc. to help control and monitor all of these low-flying personal manned and unmanned aircraft when they become as prevalent as bicycles in the sky's? If not somebody should because that day is coming and it will be a profitable venture

this design is more cost-effective than all revealed VTOL. Less power unit and simpler tilt system will reduce manufacturing costs .
combining the advantages of omniplane and tailsitter make cruise drag less than others hybrid VTOL

See the Rowe "UFO" light plane in Australia, for a circular wing though more "normal" plane.
This is like what the Navy/Vought/Zimmerman "Flapjack" naval fighter was being designed for.
Neither the V-173 nor the XF5U had powerful engines or suitable landing gear to be a VTOL tail-sitter, but Zimmerman was clearly working up to that, intended to try it, and further patent designs from Zimmerman were directly like this with landing gear that were suitable.
Note that Zimmerman didn't invent the planform: See the "Flying Heel-Lift" youtube about the Arup planes from the 1930s, which Zimmerman studied while he was working for NACA.
See also the '30s Nemeth "Parachute plane" with circular wing.
Far from being tricky to fly, or dangerous, they were stall and spin proof, could stay aloft at very high A angle at super-slow speeds. They also were not inefficient, but sleek and quick on little power.
I suspect most of the raised eyebrows at this, are because people don't know about these other circular wing planes, or have gross misconceptions about them. They do not always carry around the extreme drag due to wing-tip vortices: the vortices and the "parachute lift" they confer at very slow speeds, are temporary and elective.

I am now 86 years old and as a young boy I used to build and design model aircraft this design is not new I remember making almost a carbon copy but in balsa wood, at that time I realised the circular wing wasn't very stable; I used Jetex 50 engines which weren't very powerful so I gave up as it was just one of the many projects I had going at that time.
